To all 'whom it may concern.' ,y l

Y Be it known that I, J OHANN L'rz, a citizen of the German' Em' ire, and'residing at Essen-on-the-Ruhr, ermany, have invented certain new and useful Improvements in Means for Continuousl Operating y of which the' fo owing is a.

specification v My invention relates to an improved process and apparatus for continuously working coke-ovens, vin which the coke can slidel in consequence of'its own weight out vof the ,chamber in the oven. In order to roduce i ggod`coke,-according to the inventlon the coke is removed eriodicallyr and, for the purpose of simpli ying worki and saving aber, Ab means of an automatic apparatus,

the4 coa being supplied continuously known manner to the coke-oven. y

l A To these ends,A the coke is removed as follows The bottom of the oven is lowered into a casng.closed air-tight and located adjacent to the oven, and `the ortion of theV contents of` the chamber w ich to remain in the chamber is supported by a supporting o 'clamping device able to be throwninto o eration. The bottom is then lowered still urther,the coke located on it is removed through a lateral o `:l0

ning in the casing, the bottom is then ralsed and the supporting device cut cnt of operation. In orderrto do this automamcally the bottom fous y, until the supporting device is thrown itself'throw into gear the driving mechareerably` lowered slowly and continu- Sliun The. requisite carbonzing period'is hereby assured'and the moved bottom can nism for throwingin the `Supporting. device and for lower the bottom still further. The additional riving devices for carrymg `.out the]` emptying yof theoven can likewise A'be thrown into and out of operationy by the` mo'ved-v members, so that completely autodriven hydraulically, cocks lare opened and 'closedfpin va lfpredetelmlled order by the .mound partag The s lowicontinuous lowering ofthebsf tt0m-= Athen,l preferably eifected.

cooled lire-bars `which can beinserted .from

the outside into the caked coke in the oven, sothatA the coke is supported when the bottom 1s lowered with the coke located between it and the lire-bara y One form of, coke-oven whose coking chamber is formed as a vertical annular chamber' is represented by4 way of example in the accompanying drawing, wherein:

yFigure 1 is a vertlcal section through the coke-oven; 4

'Fig 5 is a (plan view ofthe controlling apparatustan I] Figs. 6 and 7 are respectively anfelevation and a plan of the controlling mechanism. Referring to the drawings, the coal `is supplied to the annular coking chamber a from the hopper b by way of the c' without y s belngable to escape .through the latter. he coal slides down rthe chute d into the chamber a, while the` s esca between the chute and the walls of the c a'mbera. At the lower end of the chamber a is arranged the casing e, a gas-tight 'jointbeing provided between` the two` portions of the dogblewall; this `casi surrounds the bottom" flutlie oven wh1chrests on the hydrau ic rams f connected by- 'pipes' f provided with 'a sulp ly and discharge pi 14* havin a supp yfv valve 14, and disc rge valve 2, and anadjustable control' or escape nozzle 424; and rotate `on'fthe rollers It.

Referring-now to Figs; 2 to 7 which dia.-V g'rammaticallyshow the controlling mechafnism for automatically "emptying the bot-y tom, the parts in thesefi VUs are vshown 'in' .the

Asimgrhffhefranefim am@ ros ,by them ata very low speed, 1 5+7 per minute, corresponding to the lare at their uppermost position, and the process of coking begun, they now descend with the entire charge in the oven carried preferably ratei-at which the coking proceeds. To this end vthe adjustable escape or control nozzle 24 of the cylinder of the rams is adjusted to the'suitabl speed 'of descent and remains constantly in this position, allowin a small jet of water to issue therefrom. ter the bottom has descended acertain distance, e. 1000 mm., the stop lever 25 carried by t e member 50 provided at the lower end of thel connecting member 51, which is secured to the upper end of thc ram f at 52 and descends therewith, abuts against the lever 26, moving the same from the 'position shown. in dotted 'lines to that shown in full lines in Fig. 6, whereby a three-'way cock 17 is actuated. This cock 17 is connected by a pipe 17 to the horizontal ram 53 of the h .draulic fire bars or grate i, the said pipe 1 being shown broken away in Fig. 7 and connected to the ram 53 in Fig. 1. yThe grate preferably comprises water-cooled bars, and the opening of valve 17 causes water to How be-`V hind the ram 53 and the grate to be inserted into the chamber, so that the contents of the chamber are supported thereon. 4 During the descent of the rams f, the weighted cock 20,

` which is also .connected to the rams 53 by now actuates the lever 29. which opens the d ischargav cock 1 2 connected to the rams f by the vt ree-way pipe14 above referred to, one part of which extends tb the cock 12, one to the connecting pipe f of the rams, and the other to the supply cock 14, so that the water is discharged more quickly than through vthe regulated escape nozzle, 24, the

v valve 12 being entirely open, and the=bottom can now descend rapidly Vto thev end of its stroke, the hydraulic grate 'L' novit` being closed or inserted and supporting the coke in the. chamber. The leverstops 21 and 25 are so constructed as' to be rigid when engaged at their under sides, and` pivotal when engaged at their upper sides, so that theyare inoperative during upward movement of the Shortly before the-lower end is reached, the lever 27 carried at the upper end of the-:ram f presses down thejlever 28,

' whereby the cocks 3, 4, 5 and 6 ar'eactuated,"

sothat the'cocks-'4 and`5 are opened thecocks 3 'and 6y areclosed, the

let and outlet 3 and 4 and 4 and l5 bei connected respectively iii front of and lileind the. iston of the ram g by means of pipes 54 an 55. In-

ipes 56and 57 are provided to Athe-said cocks. The piston 'rod 58 of the ram 'g now operates, being moved from .the dotted line position shown in Figs. 5 and 6 to the full line position, throwing the dellector 1 into position across the'path of the bottom g, by means of the lever 58 connected to the rod by a wrist pin 58". The deflector when not in use is locatedin a recess in the inner wall oi the The stop 7 carried by the rod 58 actuates the levers 8' and'9, which are respectively connected by members 59 andA 60 to the driving belts 61 and 62, which are moved from inop'- A erativeposition on the idle pulleys 63 and 64 to operative osition-on'the -driving pulleys 65 and-66, w ereby vthe'j bottom g is rotated with respect to the d eector-l, 'nd the scra ing belt n is brought into op ration. T e co e is deiiected by means of the deflector l throu h the lateral outlet k into the trough m, fil ed with water, from which it is removed by the scrap' g belt n over the grate ol to a conveyer device.

The fine particles of the cokecan fall into the chamber p arranged'beneath the grate o, from which they can be remov'ed from time to time.

During' the first revolution of the bottom g, a stop or projection 1a carried thereby strikes against the legs'of the lever 2, and revolves 1t through an arc of 45,.actuating action of the ram g is stopped 'and the same placed in condition for the reverse action.

The bottom g is preferably allowed to frotate Ltwice ,so that all the coke will beeifectively removed. When the stop 1, during the second revolution", of the.. bottom strikes the next finger 2"," it is again rockegthrough an arc of 45 and reverses the position of the cocks 3, 4, 5 and 6. The cock BisI opened and `allows water to enter behind the pis ton ofthe controlling ram g. The cock 4" which controlsv the outlet of Vwater from be.-

the stop 7 on the piston rod 5,8str'1kes 100 the cocks 3, 4, 5 and 6, so that the positive against the levers 8 and 9 andA disconnects the driving gear of the lbottom g andthe scraping belt n. A stop k the rod 58, and so constructed as to be rigid vduring vthe outward movement of the rod 10 also carried by.

and pivotal during the inward' movement,`

engages the lever 11, reversing the discharge lcock 12 and the lever 13, w ich opens the supply cock 14,' 'which controls, through the `will;

, Toward the end of the upward .movement of the rams f a stop 15 carried by the member 50 lifts the lever 16, which -is connected by a member 67 with the lever 26, and

a Weighted catch member 71, by means of the catch 22and the supply cock 14 is again closed, cutting olf the supply of water to the hydraulic rams f. The rams and bottom highest position, and the cycle of operation at once begins again, because Qi the slow issuanceofwater, through the constantly open nozzles 24, from the cylinders of the rams f.

I `have illustrated and described a' pretion, butit is obvious that changes may be made' therein within the spirit and scope thereof as` defined in the appended claims.
